Patent GB-292522-A (GB)
IPC: H04Q9/04
Filed: 1928-06-20
Abstract: 292,522. Akt.-Ges. Brown, Boveri, et Cie. June 20, 1927, [Convention date]. Synchronous movements.-Relates to arrangements for ensuring synchronous operation of the selector switches and distributors located at the transmitting and receiving stations of a distant control or signalling system. As shown the contact arms a of distributors ware rotated in synchronism by electric motors m, each of which drives contact discs c, d. Assuming the contact arms are at rest in corresponding positions, and it is desired to effect a selection, the appropriate selecting key (not shown) is operated and a push k is depressed to energize a relay l which energizes relays i from a battery b at the transmitting station G over contact discs d and line wires s, r. When the arms a rest upon corresponding contacts, the discs d complete the line circuit over the relays i but the circuits through the discs c are broken by insulating segments. the relay l, when energized, is held locked, and operation of the relays i closes local circuits for the motors from the batteries b. The motors are thus started and are maintained in operation by circuits completed through the discs c although the relays i are de-energized by the interruption of the line circuit at contacts d. The arrangements are such that when the arms a cooperate with the succeeding contacts of the distributors, the local circuits of the motors are opened by the contact discs c but the original circuits are again closed by the relays i upon closure of the contacts d to cause the continued operation of the motors. If one motor runs at a greater speed than the other its circuit is maintained open until the other motor has overtaken it and thereby dosed the line circuit to cause operation of both relays i. This cycle of operations is continued and synchronism established at each contact of the distributors until when the arms a arrive at contacts corresponding to the operated selecting key, a relay h is energized to unlock relay l and open the motor circuits. Several receivers may be operated by one transmitter, or one receiver may serve a number of transmitters. Instead of electric motors, electrically controlled devices of any known type mav be employed. Specification 7802/14 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that electrically controlled hydraulic or pneumatic motors may be employed. This subject-matter does not appear in the Specification as accepted.
Patent GB-423096-A (GB)
Title: Improvements in the treatment of artificial filaments, threads, ribbons and like materials
IPC: D01F2/28
Filed: 1933-06-23
Abstract: Artificial filaments, threads, ribbons, and like materials of cellulose acetate or like film-forming base, are treated so as to reduce moisture therefrom, softened by treatment with a liquid softening agent, and stretched while in a softened state.  The moisture content may be reduced by heating in the presence of dry air, or by extraction with a volatile liquid which is a non-solvent for the cellulose derivative base.  The process is applicable to materials of cellulose acetate, nitrate, formate, propionate, or butyrate, or ethyl, methyl, or benzyl cellulose, or ethyl cellulose acetate, or oxy-ethyl cellulose acetate.  The cellulose derivative may be of high or low viscosity characteristics.  The process may be carried out as a continuous operation, or the whole or part of the treatment may be performed with the material in hanks or wound on perforated bobbins.  In an example, cellulose acetate yarn is drawn from a creel in the form of a warp of threads, passed round steam heated drums and into an aqueous solution of acetone, dioxane, or diacetone alcohol, where it is stretched to twice its original length by passage in contact with rollers rotating at progressively increasing speeds.  The steam heated drums are enclosed in a chamber through which is passed a current of dry air.  Specifications 277,089, 323,790, [both in Class 2 (ii)], 370,430, and 392,185 are referred to.

Title: Image control method and apparatus
IPC: G03G15/22
Filed: 1959-05-27
Abstract: 926,361. Producing images of improved contrast from light-scattering patterns on specular xerographic or other surfaces. RANKXEROX Ltd. May 27, 1959 [May 28, 1958], No. 18105/59. Classes 97 (1), 98 (1) and 98 (2). Apparatus for producing an image of increased contrast from a pattern of lightscattering material on a specular medium comprises means for electrostatically producing the pattern; first optical means for directing the rays from a light source on to said medium, and second optical means for forming an image of the specular medium on a utilization surface, said first and second optical means being so positioned relatively to each other and to the specular surface that at least the major portion of the light from said first optical means specularly reflected from the said surface is directed through the second optical means to form on said utilization surface a dark image of the pattern on a bright image of the specular medium. The invention also comprises a method of recording an image of a pattern of light-scattering material borne on a specular medium, the method including the step of directing a beam of light on to the specular medium so that the major portion of the reflected rays are brought within a projection lens so placed that an image of the specular medium modified by the configuration of the light-scattering material is formed upon a photo-sensitive recording surface. Typically, the light-scattering material is a xerographic developer powder and the pattern is formed by developing the latent image formed by projection copying of a display on a cathode-ray tube or of a photographic film on a charged selenium or zinc oxide-in-resin layer or by X- ray exposure of such a layer. This layer may be a moving endless belt or an intermittently rotated hexagonal cylinder from which the powder image, or the residue after transfer of the image to a receiving web of paper, is removed by brushing prior to recharging for further exposure. In the arrangement shown, a display on a cathode-ray tube 70 is used to form a xerographic powder image on a continuously moving belt 73 and two separate images each formed through its own optical systems by specularly reflected light are produced on a viewing screen 116 and on a continuously rotating xerographic drum 88, the developed powder image on the drum being transferred to a web 101 on which it is fixed to give a permanent record. Specifications 679,715 and 889,202 are referred to.
